Seriously, as long as I'm in ketosis (and at a permanent <25gm of carbs per day I always am), I have this problem.

I keep a little pot of mint growing on my kitchen windowsill and just pluck a leave to chew on as I feel the need. I'll also stick a drop of spearmint essential oil in a glass of warm water (or tea, depending on my mood).

I believe that it happens while a person is becoming adapted to ketosis and if they stay in ketosis it goes away. The explanation is that one of the 3 types of ketones that are produced are being 'expelled' or wasted through respiration etc. until the body becomes adept at using them (keto adapted). Once that happens that type of ketone is only produced and then used and not 'expelled'.

I'm pretty new at this, about a month. I had a metallic / sweet taste in my mouth from about day 3-4, and it lasted about 2 weeks. I didn't do anything special for it, I do keep to 30 carbs or under per day so I'm assuming I'm in ketosis. ( much less hunger, no cravings and Keto sticks consistantly positive.

I hope your answer is the right one! I'm definitely expelling something foul via respiration. The dog has been having loose stools and I'm suspicious my breath may be the cause.

Edited to quote Dr. Eades of Protein Power: The bad breath comes from blowing off the excess ketones. Typically once people have adapted to a low-carb diet this goes away. Until then, if it’s a problem, they can use sugar-free breath mints.
